x²/a² + y²/b² = 1
In x²/a² + y²/b² = 1, if a>b or a²>b² (denominator of x² is greater than that of y²), then the major and minor axes lie along x-axis and y-axis respectively.
The centre of the ellipse will be at (0,0).
Coordinates of the vertices will be at (a,0) and (-a,0).
Length of the major axis is 2a.
Length of the minor axis is 2b
Equation of major axis y = 0
Equation of minor axis x = 0
Eccentricity e = √(1 - b²/a²)
Length of latus rectum = 2b²/a
Equations of directrices x = a/e and x = -a/e
